Figure 7. Functional and enrichment pathways analysis. (A) LncRNAs-mRNA co-expression regulatory network based-on fifteen aging-related lncRNAs. (B) A Sankey diagram was depicted to visualize the co-occurrences of lncRNAs, mRNAs and outcomes. (C) KEGG pathway enrichment analysis in high-risk group. (D) KEGG pathway enrichment analysis in low-risk group.
